Participant 1 – CNR

National Research Council of Italy

The National Research Council (CNR) is the largest public research institution in Italy, the only one under the Research Ministry performing multidisciplinary activities. Its structure include 7 scientific Departments among which the Department of Physical science and material technologies coordinates the physical-material area. The objectives of the Department include both the development of scientific thematic at the edge of knowledge and technological applications with significant economical outcomes. In the quantum science and technology field, the realization of devices for quantum sensing and information processing, with unmatchable characteristics, if compared to the classical systems has pivotal role.
